Logic Masters Deutschland e.V.

• Normal Sucoku rules apply
• Yin yang: shade some cells such that all shaded cells are orthogonally connected, all unshaded cells are orthogonally connected, and no 2x2 area is fully shaded or fully unshaded.
• There are two types of "truth tellers":
  • Digits in circles tell the truth about the total number of cells of the same shading as itself it can see in all directions combined (the cell itself is not included in this total). Cells of the opposite shading block view.
  • Arrows indicate that in that row/column, the first digit on the side of the arrow tells the truth about the number of times the shading switches in that row/column
• All truth tellers are given
